3.0 Safety warnings

1. Read and understand the entire owner’s manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This cold saw is designed and intended for use by properly trained and experienced personnel only. If yo u ar e not f a miliar wit h the pro p er a nd safe operation of a cold saw, do not use until proper training and knowledge have been obtained.

5. Do not use this cold saw for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and hold s itself harmles s from a ny injury t hat may result from that use.

6. Always wear approved safety glasses/face shields while using this cold saw. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

7. Before operating this cold saw, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and

other masonry products.

• Arsenic and chromium from chemically

treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

5.0 Cold saw features

Miter cutting head

The miter cutting head is the unit that performs the cut, and is pivoted downward manually by means of the operating lever. The head is mounted to a cast iron base, and consists of a blade support unit with guard, transmission unit, and motor. The depth of cut is set by adjusting the depth stop. The miter cutting head swivels and locks into any position within a 135º range.

Miter position lock

The miter position lock secures the miter cutting head from movement. The miter is secured when the lever is moved to the right and is released when the lever is moved to the left.

Self-center ing vise

The self-centering vise holds the work piece in place during cutting. The handwheel brings the vise toward the work piece, then the cam lever is

Figure 1

rotated for fast clamping. An anti-burr attachment is included, as well as a stop assembly for repetitive cuts of the same length.

Control panel

The panel features independent ON and OFF buttons with indicator light, a mushroom style red emergency OFF switch, coolant flow switch, and a switch for speed selection.

Flood coolant system

The coolant pump must be

submerged before operating to prevent damage to the pump.

Coolant is dispensed directly onto the saw blade from a coolant fitting on the upper blade guard. Coolant is provided through tubing from the coolant pump which rests inside the machine base. See under Maintenance for further information about proper coolants.

8.0 Installation and assembly

Tools required for assembly (not provided):

6mm hex key (Allen wrench) 12mm and 19mm open-end wrenches

Remove all packing material from around the machine. Remove screws holding the saw to the skid. Lift the machine off the skid using straps around the cast iron portions of the head (keep straps away from blade, levers, etc.).

The location should have sufficient lighting to prevent shadows around the work area. Leave enough room on all sides of the machine for movement of stock and for general maintenance work.

Figure 2

The base of the machine must be anchored to the floor by two lag bolts or studs properly anchored into concrete.

After positioning the machine, remove any cords that were used to secure the head in lowered position during shipping.

Exposed metal surfaces have been coated with a rust-protectant from the factory. Remove this using a soft cloth dampened with a good cleaner/degreaser. Do not use gasoline, paint thinner, acetone, or other highly flammable substances, and avoid using an abrasive pad as it may scratch metal surfaces.

8.1 Operating lever

Refer to Figure 3.

1. Remove the hex nut and screw from the hole at the front of the saw head (F igure 4). These fasteners will not be used again unless the machine needs to be transported in the future.

2. Insert the operating lever into the threaded fill hole. Rotate it a good distance into the hole, and make sure the final orientation of the handle grip is in a comf ortable position for the operator, as shown in Figure 3.

3. Secure the operating lever by tightening the hex nut against the saw head.

4. Push the two-pin cable connector into the receptacle sleeve on the junction box of the motor, and tighten the knurled ring to secure.

Figure 4

8.4 Coolant tank

Refer to Figure 5.

Direct the lower end of the drain hose into the basket of the coolant tank, as shown.

Fill the tank with coolant

before operating the coolant pump. Failure to do so may damage the pump.

Adjust the valve on the coolant fitting atop the blade housing, to achieve desired flow. W hen the coolant switch is in the ON position, flow starts when the drive motor is started. Turning off the coolant switch stops coolant flow.

Figure 3

8.2 Handle

Refer to Figure 4. Screw the handle into the handwheel and tighten

with the nut, using a 12mm wrench.

8.3 Exension roller

2. Calibrate the length stop: Lower the blade, and loosen the knobs on the rod holder. Then slide the upper rod into contact with the blade, and adjust the rod holder so that its left edge aligns with the zero. Re-tighten the top knob to secur e the zero setting.

9.1 Three-phase models

The CS-275 (3-phase) and CS-315 (3-phase) are rated for 230-volt only power. They are not supplied with a plug. You may either install a proper 230V UL/CSA listed plug, or “hardwire” the machine directly to a service panel.

After wiring, make sure that the blade rotates in the proper direction. If it does not, reverse two of the 3phase wires on the supply input.

9.2 Single-phase models

The CS-315-1 (si ngle phase) is rated for 230- volt only power. It is not supplied with a plug. You may either install a proper 230V UL/C SA listed plug, or “hardwire” the machine directly to a service panel.

The CS-275-1 (single phase) is rated for 115/230V, prewired for 115V and supplied with a 120-volt rated plug. It may be converted to 230V. See section 9.3.

9.3 Voltage conversion (model CS-

275-1 only)

To convert from 115V to 230V:

1. Remove the panel from the control box.

Figure 7

9.0 Electrical connections

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

On all models, if a machine is being hard-wired to a panel, make sure a disconnect is available for the operator. During hard-wiring of the machine, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the cold saw will be connected. Place a warning placard on

2. On the transformer, reconnect the L11 line from the 120V terminal to the 230V terminal (A, Figure 8).

Figure 8

3. Replace the 20 amp fuses with 10 am p fuses in the first two fus e holders (B, Figure 8 ).

4. Switch the leads in the coolant pump junction box, according to the diagram in Figure 9. (A diagram is also included on the coolant pump.)

Figure 9

5. The saw is now ready for 230V operation.

9.4 Grounding instructions

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The cond uctor with insulatio n having an outer surf ace that is green with or without yellow stripes, is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Repair or replace a damaged or worn cord immediately.

10.0 Adjustments

10.1 Miter adjustment

Refer to Figure 10.

The cold saw head has a rotational range of 135°. To adjust the miter position, follow the steps below:

1. Move the miter pos ition lock lever to t he left to release.

2. Adjust the head to the desired angle by pushing on the back of the motor to the right or left. The miter position is shown on the scale.

10.2 Vise

Refer to Figure 10.

The vise is self-centering and has a cam action lever for fast clamping. Use the handwheel to move the vise jaw about 1/16-inch away from the work piece, then rotate the cam lever to tighten.

The adjustable anti-burr arm keeps the off-cut end from flexing, which can cause burring. Use a 10mm hex key to loosen the arm for adjusting.

Refer to Figure 11. The front stop limits the blade depth of cut. The rear

stop li mits retu rn motion o f the h ead.

To adjust depth of cut:

1. Disconnect machine from power source.

2. Using two 3/4” (19mm) wrenches, loosen lock nut (A) while holding screw (B) stationary.

3. With the saw in the fully lowered position, turn screw (B) until the saw blade bottoms out at the desired level.

4. Tighten lock nut (A).

3. Loosen the cap screw (A) atop the vise, and slide the jaw as needed to accommodate the angle of the blade. Re-tighten the cap screw securely.

4. When the desired cutting angle is set, move miter position lock lever firmly to the right to secure the setting.

Two adjustable miter stops are provided for +45 and -45 degrees. Use an angle measuring device against blade and jaws, or make test cuts to verify the initial setting of these stops.

10.4 Blade replacement

Disconnect machine from the

power source before changing saw blades. Failure to comply may result in serious injury!

To change the saw blade (Figure 12):

1. Disconnect machine from power.

2. Clamp a piece of wood in t he vise, and lower the blade upon it to prevent rotation.

3. Release the linkage from the blade guard at (A) with a 5mm hex key, and rotate the guard out of the way.

4. Rem ove the screw (B) with a 10mm hex key.

NOTE: Left-hand threads; turn clock-wise to loosen.

5. Remove the blade (use gloves).

6. Secure a new blade by reversing the above steps. Make sure the direction of the teeth is correct.

IMPORTANT: A new blade requires a break-in period. Use half the normal feed speed for the operation; operate for a cutting surface of about 300 cm2 for hard materials; about 1000 cm2 for soft materials. Then resume normal speed.

12.0 Operation

Before using the machine:

 Check that safety devices (e.g. blade guards)

are in position and work perfectly and that personal safety requirements are complied with.

 Check the sharpness of the blade and verify

proper coolant flow.

Operating

1. Position work piece and close the vise; rotate the cam lever at the handwheel to secure t he setting of the vise. NOTE: A long work piece must have proper support on both ends.

2. If mitering, adjust the head accordingly and lock it in position. If making a mitered cut, verify that the blade will not contact the rear vise jaw. If it will, loosen the screw on the rear vise jaw and slide the jaw so that it clears the path of the blade, then retighten screw.

3. Turn the power on.

4. Select the blade speed.

5. Turn on coolant flow switch.

6. Start the blade by pressing the trigger on the handle grip. The trigger also activates the coolant flow.

7. Pull the operating lever to bring down the blade into the work piece. You will manually control the speed of the downstroke.

8. When the cut is complete, release the trigger and raise the head. The spring will help return the head to upward position.

9. Release the vise using the handwheel, and remove the work piece.

NOTE: When operations are complete, always return the head to upward posit ion to rel ieve stre ss on the return spring.

13.0 Maintenance

13.1 Maintenance requirements

All maintenance and cleaning

procedures must be per formed with the power switched OFF. Failure to comply may result in

serious injury! On completion of maintenance, ensure that

replaced parts and/or any tools used have been removed from the machine before starting it up.

13.2 Periodic maintenance

13.4 Lubrication

For long life and trouble free operation, it is essential that this machine is kept well lubricated. The vise and leadscrew should be oiled daily. Pivot joints and bearings should be greased weekly. Check the gearbox oil level weekly, full level is top of sight glass with head in full up position.

The gearbox oil should be changed out after the first 100 hours of operation, then after every 2,000 working hours. Drain the gearbox by unscrewing the plug on the side of the head (Figure 14). To refill t he head, r emove t he operat ing lever and pour oil into the hole. The plug also serves as the oil level sig ht glas s. F ul l leve l i s top of sig ht gl ass w it h head in full up position.

Follow local regulations for proper disposal of used lubricants.

Recommended Lubricants:

Use Texaco Meropa® 460 or equivalent. Grease fittings

Texaco Starplex® 2 or equivalent Vise and Leadscrew

Regal® R & O 68

 Remove all s w arf from th e machine,

preferably with a cloth.

 Remove chips from the coolant tank and

change coolant r egularly.

 Top off the coolant level.  Check the wear of the blade and change if

necessary (see Blade Replacement).

 Empt y the chips out of the base.  Clean the vise and lubricate all the joints

and sliding surf ac es, usi ng good quality oil.

 Attend to daily, weekly and annual

lubrication recommendations (see the Lubrication secti on) .

13.3 Coolant system

Check coolant level in the tank periodically and top off if necessary. Coolant can also be added by pouring directly on the table, which will drain into the tank through the filter plate.

This coolant system can operate with either a soluble oil base coolant or water-soluble synthetic coolant. Coolant should be changed regularly. Some recommended brands are DoAll and Lenox. These coolants are available at your local industrial distributor.

Periodically remove excess chips from the coolant tank, and clean the filter on the coolant pump.

14.0 Blade selection

When using the cold saw, it is important to select the correct type of blade for the material to be cut. This section explains the limitations and specific applications of the different types of blades.

14.1 General characteristics

Fine Tooth Pitch – used for thin wall materials such as sheet steel, tubes and profiles.

Coarse Tooth Pitch – used for large cross-sections, and for soft materials (aluminum alloys and soft alloy s i n ge ner al).

14.2 Determining proper tooth p itch

Proper tooth pitch depends on:

a) the size of the section; b) the hardness of the m aterial; c) wall thickness.

Solid sections call for blades with a coarse tooth pitch, while small cross-sections require blades with finer teeth. This is because when cutting walls of small cross-section (1–7mm) profiles, it is important that the number of teeth actually making the cut should not be too few, otherwise the effect obtained will be one of tearing rather than of chip removal, leading to a large increase in shearing stress. On the other hand, when cutting thick materials or solid sections using an excessively fine tooth pitch, the chip collects as a spiral inside the g ullet , and s ince f ine t ooth p itche s have s mall gullets, the accumulated chip will exceed the gullet capacity and press against the walls of the workpieces, resulting in poor cutting (same situation with soft materials), greater shearing stress and hence breakage of the blade.

speed depends on the cross-section of the material. Solid or thick-walled materials (thickness>5mm) can therefore be cut at high speed providing there is sufficient swarf removal by the blade, while thin-walled materials such as tubes or thin profiles must be cut with a low feeding speed.

A new blade requires a breakin period, during which time about half the normal feeding speed should be used.

14.4 Coolant

The cooling fluid ensures that t he blade teeth and material in the area of the cut do not overheat. The fluid must be an excellent lubricant so as to prevent abrasion of the teeth and welding of the chips to the teeth (seizing).

14.5 Blade structure

For non-ferrous metals, it is common to use circular saws with a brazed hard metal HM cutting edge, consisting of a disc made of alloy tool steel (71Cr1) on which the shape of the teeth and the seats for the cutting edges are made of W idia K10. These saws have shown excellent wear resistance but low resistance to impact, which is in any case a minor problem with non-ferrous materials.

Table 3

A larger pitch should be chosen when, as a result

of the shape of the piece to be cut, the crosssection at any given point exceeds the average cross-section given above.

14.3 Cutting and feeding speed

The cutting speed and the head feeding speed are limited by the amount of heat generated near to the points of the teeth. If the head feeding speed is too high, the cut will not be straight in either the vertical or the horizontal plane. As we have already said, the cutting speed depends on the strength (kg/mm2) and hardness (HRC) of the material and the dimensions of the thickest section. The feeding

Table 4

14.6 Types of blades

The blade required for t he cold saw is of HM hard steel type since the machine is to be used for cutting non-ferrous materials. In addition to the size and pitch of the teeth, however, the blades also have different geometric characteristics in accordance with their particular use:

tooth cutting angle – may be negative or positive tooth sharpening – m ay be BW with an alternate

raked tooth or C with a roughing tooth raked on both sides and a non-raked finishing tooth

tooth pitch – the distance between the crest of one tooth and the crest of the next tooth (tooth pitch = T)

sections.

Figure 17

Short swarf material such as brass, bronze, aluminum and hard cast iron require smaller cutting angles because the swarf becomes crushed immediately and the rake angle has little effect during the cutting stage.

The cold saws use discs with positive cutting angles for cutting solid materials and wit h negative cutting angles for cutting hollow profiles. This is because, as a result of the high cutting speeds, even with non-ferrous materials the tool ”strikes” against the wall of the profile to be cut several times, thus requiring a cutting edge with a larger resistant section.

Figure 16

POSITIVE AND NEGATIVE CUTTING ANGLES

The cutting angle may vary from positive to negative depending on the cutting speed, the profile and the type of material to be cut.

A positive angle determines better penetration of the tool and hence lower shear stress and greater ease of sliding for the swarf over the cutting edge. On the other hand, the cutting edge has lower mechanical resistance, so that as the breaking load of the material to be cut increases, the cutting angle decreases from positive until it becomes negative, thus offering a cutting edge with a larger resistant section.

Figure 18

Circular saws can also be characterized by other parameters such as the whine reduction feature, which cuts down noise at high speeds, or expansion, which compensates for the pushing of chips inside the cutting edge, thus reducing the thrust on the walls of the material to be cut.

Check the blade speed and the type of blade you are using. Also be aware of feed pressure.

With a new blade it is necessary to start cutting at half feeding speed. A f ter the wea ri ng-in period ( a cutt ing surface of about 300 cm2 for hard materials and about 1000 cm can be brought up to normal values.

The s war f wedges into the bot t om of t he teeth c ausing excessive pressure on the teeth themselves. Use a blade wi th coars er to oth pitch.

The surface of the cut may have undergone work hardening. When starting work again, use a lower blade speed and reduced feed pressure. A tooth from the old blade may be left in the cut: check and remove before starting work again.

Any movement of the work piece during cutting can cause broken teeth: check the vise, jaws and clamping pressure.

The blade runs over the material without removing it: increas e feed speed.

The teeth slide over the materi al without cutti ng it: reduce the blade s peed.
